Abstract

The method involves connecting a load (51) to a supply network (61). Control positions of a control element (60) of domestic equipments selected by a user are registered and acquired by a central control unit (53) and are stored as a scene. A scene-type activation status of the load is monitored by an activity detector. The scene-type activation status of the monitored load is assigned to the stored scene. The control positions are automatically retrieved during detection of the activation status, and the control element of the domestic equipments are controlled.

Description

Technical area

The invention relates to a method for controlling building services equipment, which are each provided with a control to control activation, wherein one or more of the building services equipment connected to a supply network include consumers and selected by a user control settings of the controls of the building services equipment from a central Control unit registered or learned and stored as a scene, the control positions retrieved when needed and the controls are regulated accordingly.

State of the art

For switching on and off, as well as the control and regulation of building services such as electrical consumers in homes or other buildings are numerous embodiments of wiring and operation in the market. Typically, controls such as toggle switches, on / off pushbuttons, rotary or monostable pushbuttons are mounted in one or more easily accessible locations, which provide suitable wiring to allow circuits to be opened and closed, e.g. B. for switching on and off a lighting, and devices can be operated (eg activation stages of a fan). To simplify and increase the comfort of the term "scenes circuit" certain consumers to so-called "scenes" summarized, which can be manually retrieved by a single control element, such as. B. at US 4,924,151 (Lutron Electronics Co., Ic.) Or WO 2001/50684 (C-Smart LLC). For each scene, a separate control is usually required. An operating element is a button in the simplest case. Today, under the heading "intelligent living", there are also more elaborate control panels with graphic, z. For example, menu-driven operating aids and touch panel accessibility. All of these installation techniques are proven, but in addition to the requirement for manual control units require a large amount of cabling (with conventional cabling) or a large programming and configuration effort (in BUS-controlled systems).

Typical scenes are for example "cooking", "television", "office work", "party". Scenes are characterized by the fact that they often represent recurring situations that require a specific setting of building services (elements for lighting, shading, heating, ventilation of the living space). In the case of known installation solutions, the settings of the building services equipment desired for the respective scene are activated as required by a resident or user by the occupant acting on at least one control point. The technical facilities are then controlled according to a scene logic implemented in the installation. This results in the disadvantage that a resident must visit a control unit in order to select a scene. This requires a large number of operating units, to ensure good operability throughout the entire home and building automation system. Although remote controls provide a certain remedy, but also in this case, the scenes must still be manually activated.

Presentation of the invention

The object of the invention is therefore to provide a the technical field mentioned above associated process and an arrangement for carrying out the method, which allow an improved and more comfortable choice of scene.

The solution of the problem is defined by the features of claims 1 and 7. According to claim 1, the invention provides a method for controlling building services. The building services equipment are provided for controlled activation each with a control and have one or more connected to a utility consumers. To control are selected by a user control settings of the controls registered or learned by a central control unit and stored as a scene, the control positions are retrieved when needed again and the controls of the facilities are controlled accordingly. According to the invention, activation states of one or more of the consumers are monitored by a respective activity detector. Furthermore, scenario-typical activation states of one or more monitored scenario-typical consumers are assigned to a stored scene. Upon detection of the scene-typical activation states of scene-typical consumers belonging to the scene stored control settings are automatically retrieved and the affected controls the home automation equipment regulated accordingly.

The invention thus provides a method which allows automatic recognition of scenes and according to which desired settings of building services equipment automatically, d. H. without action of the resident, done correctly and - if the scene changes - according to the settings of the new scene changed.

All of the technical designs of components of the home or building automation system described below in connection with the method can also be used as possible embodiments, independently of the method according to the invention be transferred to the inventive arrangements. Conversely, method steps described in connection with the arrangement are also associated with the method according to the invention.

According to the invention, the building services equipment to be controlled for the scene are controlled via a home or building automation control center, or in general a central control unit. For example, light sources, heaters, kitchen appliances such as cookers, extractor hoods or fans, but also TV sets, computers or other electrical consumers are considered as technical installations. But it is also conceivable, for. As heating or hot water boiler and water or gas flow via the control unit to control. Further, even curtains or curtains or other screens can be controlled by the control unit and z. B. be activated to darken a room.

The respective building services equipment are provided with controls that allows a regulation activation of the respective device. The controls can be z. B. according to the in the EP 1 734 636 A2 (Adhoco AG) and installed in the building. But it is also conceivable to provide the controls as external and largely independent units, which are arranged between the consumer and a power outlet of the supply network, for. B. as an adapter or as an intermediate cable. The controls are preferably equipped with a local intelligence such that a current switching / control state or a manually triggered by a user control or switching operation can be transmitted via a communication system to the control unit and detected by this and vice versa due to a tax Signal of the control unit a switching or control process can be triggered. For better clarity, here and below under control process both continuous changes of an activation state such. B. in the dimming of light as well as binary switching operations such as turning on / off a consumer understood.

The home or building automation center or the central control unit is preferred according to a system as in EP 0 900 417 B1 (HTS High Technology Systems AG). Such a control unit recognizes, learns and independently stores the settings made by the occupants or desired in this scene settings of the building services. Recognizing and learning the preferred settings the house-technical facilities is preferably carried out by a z. B. due to neural network technology achieved learning ability of the central control unit. Next, the control positions of the controls of the building services of a stored scene can be recalled when needed (scene selection) and the technical facilities or their controls are controlled accordingly. In conventional systems, the scene selection is done manually, ie by a user interaction with the control unit or via control elements connected to the control unit or a remote control. Such operating elements, as well as operating elements for activating a building services equipment, can continue to be provided in a control unit according to the invention. However, the invention goes new ways in which a manual scene selection is no longer required and is automatic, ie the selection of the scene is done independently by the control unit without direct user interaction.

For automatic scene selection, according to the invention, an activity of a number of consumers of the building services equipment is monitored. In this case, for example, only one or all and also an arbitrary subset of the consumers can be monitored. For this purpose, the monitored consumers are each assigned an activity detector which can measure a consumption of the respective consumer, or can recognize on the basis of a consumption whether a consumer is switched on or switched on or off. In particular, the activity detector may detect an activation state of the consumer, which is limited to the binary states "on" or "off". However, it is also possible to monitor continuous gradations of activation, such as when dimming light, and, if appropriate, to assign this to a scene as a typical activation state of a typical consumer. The monitoring is preferably carried out by the central control unit, to which the activity detectors are connected, for example via the communication system. It is here z. B. conceivable that the control unit periodically polling by so-called "polling" the status of the activity detectors or the respective consumer. However, embodiments in which the activity detectors independently send a signal as soon as there is a change in the activation state of the consumers are preferred. Other conceivable embodiments include current, ie, for example, occurring at a certain frequency, messages of the state of activity of the monitored consumers by the activity detectors.

If an activity detector detects that the corresponding consumer has been activated or deactivated or an activation state of the consumer has changed, this information is transmitted to the control unit via the communication system. If the activated consumers are consumers which are defined as typical for a scene, then the control unit automatically retrieves the stored settings of the associated scene and triggers the corresponding regulation or switching processes in the controls of the household appliances. As scene typical here consumers are to be understood, which for a certain scene z. B. necessarily required, or are activated with a high probability in a particular scene. In a possible scene "cooking" is z. B. to expect that a hotplate or a stove is activated. The hotplate can thus be assigned as a typical consumer of the scene "cooking" and an associated scene-typical activation state is "activated". Similarly, activating a TV for an associated "television" scene or turning on a computer for the "office work" scene is typical. If the hotplate or the TV is activated, the respective activation state of the consumer is detected as typical for the corresponding scene and the corresponding scene is triggered. Typical consumers with associated scene-type activation states can be identified for a variety of scenes and thus provide a far-reaching and reliable criterion for scene selection.

For automatic scene selection, according to the invention, one or more of the monitored consumers of the building services equipment is assigned to a scene as a typical consumer. Associated with this is the assignment of scene-typical activation states of typical consumers. The activation states of the typical consumers can thereby correspond to complex activation patterns, whereby a great versatility of the criteria for scene selection is achieved. For example, three typical consumers A, B, C with scene-typical activation states A "activated", B "disabled" and C "activated" can be assigned to a given scene. According to the invention, in this case, the associated stored scene is retrieved and the corresponding control positions of the controls are triggered when the typical consumers A, B and C have been activated or deactivated according to this scheme. It is understood that also methods with the scene assignment are any number of typical consumers with scene-typical activation patterns of any complexity within the scope of the invention.

However, it is preferred for the sake of clarity and ease of association that a scene is associated with exactly one typical consumer with scene-typical activation state, as in the "television" or "cooking" examples described above, for example. A stored scene is retrieved when the exact one associated typical consumer is placed in the scene-typical state of activity. This simple assignment results in a clear and clear criterion for the recognition and selection or the retrieval and activation of a stored scene.

The assignment can be made automatically according to the invention. The control unit identifies in this case independently in the monitored consumers due to their activation states typical consumers of a scene and automatically assigns these together with the activation states of the current scene as scene-typical. Such control or recognition may represent a preferred variant of the inventive method for certain requirements.

However, in the method according to the invention, typical consumers of a scene with associated scene-specific activation states are preferably manually preset or permanently programmed. The recognition and / or learning of a scene is thus particularly simplified in that the central control unit can use the consumers typical of the scene as a reference. The control unit learns the settings made by the user during operation of the typical loads and recognizes that the settings made belong to the current scene due to the scene-typical activation states of the typical consumers. With the method according to the invention, a parallel use of learned and permanently programmed scenes is thus also possible. It is Z. B. conceivable that the settings certain home automation equipment for a scene fixed, that can not be changed by the learning process, can be specified, while the settings of other belonging to the same scene home automation devices are learned in a known or described above. The fixed settings can then z. B. manually by a user or

Technicians can be programmed while the corresponding learned settings can be adjusted by the control unit independently. It is thus a coexistence of fixed programmed and learned scenes or partial scenes possible, which is only possible by the inventive identification of a typical consumer of a scene as a reference.

Basically, it is not necessary that all scenes have a typical consumer. There are certainly scenes conceivable in which no typical consumers are assigned and which still z. B. must be manually selected or activated. Conceivable here are, for example, scenes that are activated at fixed recurring times. However, in order to be able to exploit the advantages of the automatic scene selection according to the invention to the greatest possible extent, it is preferable if at least one typical consumer with scenes-typical activation state should be assigned to each stored scene. In particular, each selectable stored scene is associated with a typical consumer, i. H. any scene whose fetching and activation is not fixed and which is done by the user in conventional systems. With the assignment of a typical consumer with associated scene-typical activation state for each selectable stored scene, the invention enables a largely automated scene selection for substantially all of the stored scenes. It therefore requires no direct interaction of the user with the control unit resp. with a control connected to the control unit to recall a scene or change the current scene.

The monitored consumers preferably include electrical consumers that consume electrical power provided by the utility grid. The monitoring of the activity of a consumer is in this case preferably by measuring the electric current to detect an electrical power consumption of the respective consumer. The activity detectors are designed to carry out the monitoring in such a way that they can measure or determine an electrical power consumption by the corresponding consumer. For this purpose, the activity detector preferably comprises a sensor which measures the current flow. Any energy required for the operation of the activity detectors can be realized in this case directly with a power supply from the supply network.

However, a monitored consumer can also be, for example, a water consumer or a gas consumer. The monitoring of the activity of the consumer in this case comprises the measurement of a flow rate of water or of gas. The activity detector is then a simple flow meter, which z. B. measures the operation of a shower or a gas stove due to the water or gas flow. For a possible scene "showers" would be a typical consumer z. As the shower tap, when activated, the corresponding stored scene is retrieved. Accordingly, for a scene "cooking" the gas stove would be a typical consumer. The associated supply network is then z. As a installed in the building water supply system or a gas line.

While monitoring is different, i. H. not electrical, consumer in certain cases may well represent a preferred modification of the inventive method is due to the greater choice of possible electrical consumers in z. B. a household in a monitoring of electrical consumers ensures greater versatility. However, it is quite conceivable that in the inventive method, a parallel application of activity detectors for monitoring on the one hand electrical consumers and on the other hand of other consumers in the same arrangement is preferred. The method in this case includes in parallel the monitoring of electrical as well as of other types of consumers.

Many of today's electrical consumers, for example, from the consumer electronics (TV), office computer equipment (PC, screen, printer) and kitchen appliances (coffee maker) have a so-called standby operation. In standby mode, the device is largely switched off, but has some basic activity to z. B. faster to be ready. As has been shown, devices in standby mode, one of the largest consumers of electrical energy in z. The method according to the invention therefore preferably provides for the consumer to be disconnected from the supply network when a monitored consumer is not activated during a period that can be predetermined by a user or is registered or learned by the control unit.

In an advantageous embodiment, the activity detectors therefore have additional power switches (eg relays) or are coupled to such components. In order to It is possible to disconnect the consumers who are typical for the scene from the supply network during extended periods of non-use in order to reduce or eliminate energy consumption in standby mode. The non-activation is preferably measured by the activity detectors or their sensors. It is z. B. conceivable that the activity detector is provided with a local intelligence, which allows him to determine the non-activity of the consumer during a predetermined period and optionally separate the consumer through the circuit breakers from the supply network. Communication with the control unit is not required in this case. However, it is quite conceivable that the periods for a separation from the supply network for the various monitored consumers are controlled centrally in the control unit and the power breakers of the activity detectors are controlled by the control unit. The periods of deactivation-relevant non-activity that may be specific to the particular consumer may be e.g. B. by the control unit on the basis of the frequency of activation of a consumer by a user or manually specified.

According to claim 7, the invention provides an arrangement for a home and building automation system to solve the inventive task, which is particularly suitable for carrying out the inventive method described above. The arrangement comprises a control unit, a communication system and building services equipment, wherein the home automation equipment for the controlled activation are provided with control elements and have one or more of the building services equipment connected to a utility consumers. The controls are connected via the communication system to the control unit. The control unit, the communication system and the building services equipment are designed and cooperate in such a way that the control unit can register or learn and store as a scene user-selected control settings of the controls of the building services equipment. The control unit is designed such that it can retrieve the control positions of a stored scene when needed again and regulate the controls of the building services equipment accordingly. According to the invention, the arrangement is characterized by activity detectors, which a or more of the consumers associated with their monitoring. The activity detectors are connected via the communication system to the control unit.

By monitoring consumers with activity detectors and their connection to the control unit is achieved that the control unit is constantly informed about an activity state of the monitored consumers or can be informed. The activity detectors are configured to recognize that the associated consumer is being commissioned and may report this to the home or facility automation center.

In order to enable communication between control elements of the building services equipment and the central control unit in carrying out the inventive method, a communication system is provided. The communication system preferably comprises a wireless radio network or a powerline network; The communication can be done in other versions, but also via conventional control or BUS cable. The communication system not only allows communication between the controls and the central control unit, but other components such as possibly existing sensors, such. B. motion sensors, smoke detectors or thermostats, or even control units or the activity detectors described below are networked via the communication system with other components of the building system.

In order to simplify the arrangement, the communication between the activity detector on the one hand and the control center and the associated technical facilities on the other hand preferably via the same communication system, via which the sensors or controls or switching devices are connected to the central control unit.

Furthermore, the control unit is preferably designed such that, upon changes in the activation states of the monitored consumers, it is automatically determined whether the changed activation states correspond to scene-typical activation states of typical consumers of a stored scene. The control unit is further designed such that they automatically retrieve the stored control settings of the corresponding scene and the communication system controls the home automation Facilities, provided that it is found that the typical consumers of the scene have scene-typical activation states.

In a preferred embodiment, the home or building automation center or the control unit as a system according to the above-mentioned EP 0 900 417 executed. The recognition and learning of the preferred settings of the building services equipment is carried out by a z. B. due to neural network technology learning central control unit. Such a control unit recognizes and learns the regulation settings of the building services or the control elements that are important for the scene during the operation of the typical consumer.

While the activity detectors may be implemented in various ways, a preferred embodiment is designed such that the activity detector can be installed between a port of the supply network and the consumer. There are z. B. embodiments in the form of an intermediate plug with a plug and a socket conceivable, wherein the plug z. B. plugged into a wall outlet of the supply network and a connection of the consumer can be connected to the socket. Other conceivable embodiments can z. B. be a power strip or even embodiments as built-in modules, which z. B. can be installed as a switch or wall socket fix. Such embodiments are preferred because no manipulation or structural measures at the consumer are required. Each consumer can be provided in a simple way with the activity detector, simply by the adapter plug or the corresponding embodiment between the supply network and consumer is switched.

Further possible embodiments relate to retrofit sets with which the respective consumers can be provided. Although retrofit kits have the advantage that the activity detectors z. B. can be connected to the electronics of consumers. For example, user interactions with the consumer may be forwarded directly to the activity detectors. The disadvantage, however, is the structural complexity to install the activity detector in the consumer and connect to the consumer-to-consumer electronics.

Is it a monitored consumer to a non-electrical consumer such. B. a water or gas consumers, the activity detector can be designed as a fitting, which z. B. between water or gas tap and the corresponding supply network can be switched.

The activity detectors preferably have a certain local intelligence, which makes it possible to measure the measured activity z. B. forward depending on the case or to initiate simple measures directly without consultation with the control unit. Preferably, therefore, in each case a programmable logic unit is integrated into the activity detectors, which has the desired local intelligence due to programming. Depending on the requirements, the logic units or the activity detectors can be provided with a different level of intelligence, which makes the building automation system versatile.

Alternatively, the activity detectors can also be designed without a significant logic unit. The activity detectors transmit in this case z. B. only measured activities without prior treatment. Such an embodiment of the activity detectors but has the disadvantage that, without prior preparation and / or interpretation of the measured data z. B. the network traffic and the central control unit are more heavily burdened.

Ways to carry out the invention

In Fig. 1 Fig. 1 shows a section of a conventional decentralized arrangement 1 for a home or building automation system, as known from the prior art. The arrangement 1 has a line-connected BUS system 2 for communication between different components of the automation system, which will be described in more detail below. The BUS system 2 comprises a backbone 7, to which the various components are connected.

The arrangement 1 comprises two operating elements 3.1 and 3.2 for scene selection, which are connected via a respective coupling unit 6.1 or 6.2 to the bus system 2. The operating elements 3.1 or 3.2 in each case together with the associated coupling unit 6.1 or 6.2 are designed as operating units 14.1 and 14.2, which are connected to the BUS system 2.

Furthermore, the arrangement 1 comprises two further operating elements 11.1 and 11.2 for actuating in each case one consumer 4.1 or 4.2 by a user. The controls 11.1 and 11.2 are connected via coupling units 6.3 and 6.5 to the bus system 2. The operating elements 11.1 and 11.2 together with the associated coupling units 6.3 and 6.5 are each designed as an operating unit 13.1 or 13.2.

The consumers 4.1 and 4.2 are electrical consumers and are connected via a respective supply connection 9.1 or 9.2 to a power supply network 8. The power terminals 9.1 and 9.2 each have an intermediate activator 10.1 or 10.2 in the form of current regulators, which is connected to the control system via an associated coupling unit 6.4 or 6.6 to the bus system 2 (for consumers who are not electric, such as a water or gas consumers, includes a possible activator z B. an electrically controllable valve). The current regulators 10.1 and 10.2 regulate the flow of current in the line terminals 9.1 and 9.2 and are formed together with the associated coupling units 6.4 and 6.6 each as a control 12.1 and 12.2 in the sense of a switching or control box with iokaier intelligence and BUS interface. The controls 12.1 and 12.2 can thus be connected directly to the bus system 2.

Consumers 4.1 and 4.2 are each part of a (not shown) domestic technical device, the home automation devices are provided to control activation with the controls 12.1 and 12.2. The controls 12.1 and 12.2 may for example also be integrated into the respective household appliances or be provided externally as a separate unit.

The coupling units 6.1-6.6 each have a programmable integrated logic unit 5.1-5.6, which allows programming with a local intelligence. In addition, the connection of the various components such as controls 3.1 / 2, 11.1 / 2 and current controller 10.1 / 2 to the bus system 2 via the coupling units 6.1-6.6. The coupling units 6.1-6.6 thus serve, on the one hand, to communicate the operating elements 3.1 / 2, 11.1 / 2 and the current regulator 10.1 / 2 and, on the other hand, implement a scene logic of the arrangement or of the building automation system on the basis of the programmed logic units 5.1-5.6.

The control of the consumers 4.1 and 4.2 by a user via the controls 11.1 and 11.2 via the coupling units 6.3-6.6 and the bus system 2. The logic units 5.3-5.6 are programmed for this purpose that an actuation of the control element 11.1 or 11.2 on the Current regulator 10.1 and 10.2 has a corresponding change in the activation state of the respective consumer 4.1 or 4.2 result. If, for example, the operating unit 11.1 is actuated to activate the consumer 4.1, the coupling unit 6.3 outputs the corresponding instruction addressed to the coupling unit 6.4 to the BUS system 2. The affected coupling unit 6.4 recognizes the addressing and extracts the associated information. The coupling unit 6.4 interprets the instruction and actuates the current regulator 10.1 such that the desired control position is set and the consumer 4.1 is activated accordingly or optionally deactivated.

The controls 3.1 and 3.2 are used to select or control two different preprogrammed scenes of consumers 4.1 and 4.2. For this purpose, the activatable by the control element 3.1 or 3.2 scene in the logic unit 5.1 and 5.2 of the associated coupling unit 6.1 or 6.2 is stored. Upon actuation of one of the controls 3.1 or 3.2, the corresponding stored control settings of the scene are retrieved and given by the coupling units 6.1 and 6.2 as appropriate instructions for the corresponding control of the consumer 4.1 and 4.2 on the bus system 2. From there, the addressed coupling units 6.4 and 6.6 remove and utilize the instructions and regulate the consumers 4.1 and 4.2 accordingly.

FIG. 2 shows an inventive arrangement 20, which partially the arrangement 1 of Fig. 1 equivalent. Like the arrangement 1, the arrangement 20 also has a BUS system 2 with a backbone 7.

The coupling units 6.3-6.6 and the controls 11.1-11.2 and the consumers 4.1 and 4.2 are essentially as in the illustration of Fig. 1 however, programming of the logic units 5.3-5.6 differs from programming in the array 1 (see below).

In contrast to the arrangement 1, the BUS system 2 in the arrangement 20 is connected to a central control unit 21. In addition, the control units 14.1 and 14.2, which are no longer required according to the invention, are omitted for the selection of preprogrammed scenes.

In the arrangement 20, however, a further consumer 15 is present, which is connected via a supply connection 9.3 to the supply network 8. The supply connection 9.3 is monitored by an activity sensor 22, which is connected via a further coupling unit 6.7 to the BUS system 2. The coupling unit 6.7 has an integrated logic unit 5.7, which allows programming of the coupling unit 6.7 with a local intelligence. The activity sensor 22 is formed in the illustrated embodiment as a sensor 22 for measuring an electric current. The sensor 22 may be z. B. be introduced into the supply connection 9.3 or the line connection z. B. from the outside. In this case, all known sensors 22 suitable for current measurement can be used. The sensor 22 together with the coupling unit 6.7 is combined into an activity detector 23, which can be connected directly to the BUS system 2.

The logic units 5.3-5.7 of the coupling units 6.3 to 6.7 are programmed in such a way that the local intelligence achieved with them is essentially limited to the transmission of events of the operating elements, activators, sensors or other conceivable components or a transmission of instructions of the control unit to the same. The coupling units 6.3-6.6 thus have with respect to the corresponding programming in the arrangement 1 of Fig. 1 reduced local intelligence and are no longer significantly involved in the implementation of the scene logic. The control positions for different scenes of the consumers 4.1 and 4.2 are stored in the central control unit 21 and are retrieved as needed. The instructions for activating scene control settings are also carried out by the control unit 21. D. h. the entire scene logic of the arrangement 20 is thus implemented according to the invention in the control unit 21 and thus centralized.

The direct control of the consumers 4.1 and 4.2 by the controls 11.1 and 11.2 takes place in the arrangement 20 in contrast to the arrangement 1 via the control unit 21. The control units 13.1 and 13.2 transmit an actuation of the controls 11.1 and 11.2 to the control unit 21, which on it the corresponding instructions to the controls 12.1 and 12.2 transmitted. However, it is also conceivable that a local intelligence of the coupling units 6.3-6.6 is maintained, which allows the same direct control as in the arrangement 1, d. H. without the involvement of the central control unit.

In contrast to the arrangement 1 of Fig. 1 the selection of a scene in the arrangement 20 is no longer made by manual selection via a corresponding control element. According to the invention, a stored scene is detected or selected by bringing at least one consumer typical of the scene into a scene-typical activation state.

In the arrangement 20, the consumer 15, which is monitored by the activity detector 23, forms a typical consumer 15 of a scene stored in the central control unit 21. If the typical consumer 15 is brought into the scene-typical activation state, the sensor 22 reports the corresponding activation state to the coupling unit 6.7, which transmits a corresponding message to the control unit 21 via the BUS system 2. The central control unit 21 recognizes that the activated consumer 15 is typical of a stored scene and that the typical consumer has been brought into a scene-typical activation state. The central control unit 21 retrieves the associated stored scene settings in the sequence. Due to the stored scene settings (i.e., control settings of the scene), the control unit 21 transmits corresponding instructions to the coupling units 6.4 and 6.6 via the BUS system 2. The coupling units 6.4 and 6.6 cause via the current regulator 10.1 and 10.2 according to the instructions, the regulation of the consumers 4.1 and 4.2 according to the selected scene.

The activation of the scene settings thus takes place without direct interaction of a user with the home or building automation system, but on the transition of scene-typical consumer 15 in the scene-typical activation state.

FIG. 3 also shows an inventive arrangement 30, which largely the in Fig. 2 illustrated arrangement 20 of Fig. 2 equivalent.

In contrast to Fig. 2 however, the BUS communication system 2 is replaced by a radio communication system 31. The control units 13.1 and 13.2, as well as the controls 12.1 and 12.2 and the activity detector 23 communicate in the arrangement 30 via the radio system 31 directly to the central control unit 21. Coupling units 6.3 to 6.7 and the associated logic units 5.3-5.7 are in the illustration of Fig. 3 integrated into the components 12.1-12.2, 13.1-13.2 and 23 and no longer shown separately. For connection to the radio system 31, the coupling units 6.3-6.7 integrated in the components 12.1 / 2, 13.1 / 2 and 23 have the corresponding transmitting and / or receiving means. The associated logic units 5.3-5.7 are programmed as in the arrangement 20 such that the components 12.1 / 2, 13.1 / 2 and 23 have a required for the transmission of events and for receiving instructions from the control unit 21 local intelligence.

The messages of the components 12.1 / 2, 13.1 / 2 and 23 to the central control unit 21 and instructions of the control unit 21 to the components 12.1 / 2, 13.1 / 2 and 23 via the radio system 31. The detection of an activation change or scene-typical activation of the typical consumer 15 and the scene selection triggered thereby takes place analogously to the arrangement 20 of FIG Fig. 2 with the difference of wireless radio transmission.

FIG. 4 shows a schematic detail view of an activity detector 23 as z. B. in the arrangement 20 or 30 for monitoring the consumer 15 is used.

The activity detector 23 comprises the activity sensor 22 and the coupling unit 6.7 with integrated logic unit 5.7. The activity detector 23 is connected via the coupling unit 6.7 to a communication system 41, which, for example, the bus system 2 of Fig. 2 or the radio system 31 of the Figure 3 equivalent. The activity detector 23 monitors the supply connection 9.3, with which the consumer 15 is connected to the supply network 8.

In the embodiment of the Fig. 4 the activity detector 23 is supplemented according to a preferred embodiment of the invention with a circuit breaker in the form of a circuit breaker 40. The circuit breaker 40 is connected to the coupling unit 6.7 and designed such that it can interrupt a power or power supply via the supply terminal 9.3 to the consumer 15 42.

If the logic unit 5.7 of the coupling unit 6.7 programmed accordingly, so the activity detector 23 at a predetermined or learned from the logic unit 5.7 period of non-activation of the consumer 15 disconnect this independently from the supply network, for example, to prevent unnecessary standby operation of the consumer 15. However, it is also conceivable that the activity sensor 22 notifies the non-activity via the coupling unit 6.7 to the central control unit 21 and optionally sends an instruction to the circuit breaker 40, which is received by the coupling unit 6.7 and passed to the circuit breaker 40. The circuit breaker 40 interrupts or restores, as instructed, a power supply to the load 15. A restoration of power after one Separation from the supply network, for example, via a (not shown) additional control or a control unit are triggered.

Fig. 5 shows a possible embodiment of an inventive arrangement 50 with a TV set 51, a home automation device comprising a light source 52, a central control unit 53 and a wall connection 54 of an electrical supply network 61. The central control unit 53 communicates via a radio system 55 with a control 60, z. As a switch, the light source 52 and an activity detector 56 for monitoring the TV 51st

The central control unit 53 is formed in the illustrated embodiment as a wall-mounted unit. The activity detector 56 is designed as an intermediate plug 57, which is connected via a connection cable 58 to the wall connection 54 of the supply network 61. The TV set 51 is connected with an associated connection cable 59 to the activity detector 56 designed as an intermediate plug 57.

A stored in the control unit 53 scene "television" of the building automation system of the assembly 50 thus includes as a typical consumer the TV set 51 and an associated activation setting of the light source 52. It is z. B. conceivable that for the scene "television" the activation of the light source 52 a predetermined z. B. should have darkened value. Upon activation of the TV 51, the activity detector 56 measures an increase in the power consumed by the TV 51, or a current flowing through the line 59. The activity detector 56 sends the information about the activation event to the control unit 53 via the radio system 55. This recognizes the activated TV set 51 as a typical consumer and the associated activation state "activated" as scene-typical for the "television" scene and calls up the corresponding stored control positions for the control 60 from. The control unit 53 sends via the radio system 55 corresponding instructions for activation to the control element 60 of the light source 52, which converts the desired setting of the activation of the light source 52.

If the user is not satisfied with the activation state of the light source 52, he can adjust the setting z. B. change over a connected via the radio system 55 wall-mounted control element 62 or directly via controls of the control unit 53. The operating element 62 causes the control element 60 either directly or via the control unit 53 (notification of user input to control unit 53, control unit instructs control 60) to adjust the control position of the control element 60 of the light source 52 according to the user's request. In any case, the new setting is transmitted to the control unit 53, which registers the new control position. Due to the activated TV 51, the control unit 53 recognizes that the new control position belongs to the scene "television". The typical consumer "TV 51" thus provides a reference for the settings of the scene "television". The control unit 53 does not adopt the new setting identical. Rather, the new setting is learned only after repeated adjustments of the settings by the user, because only then a sufficient significance of the new control position is guaranteed. A corresponding adaptive control unit is for example in the EP 0 900 417 B1 (HTS High Technology Systems AG). Of course, the user can at any time override the stored or learned control positions of the control unit 53 and force a saving of the manually selected setting.

When the television set 51 is switched off again, the activity detector 56 notifies the control unit 53 of this deactivation event. The control unit 53 then causes a control position of the light source 52 and the control element 60 according to z. A default scene or an activation set prior to the selection of the "television" scene.

If the TV set 51 remains inactive for a long time, the activity detector 56, independently or via the control unit 53, causes an operation of a circuit breaker integrated in the activity detector 56 (see FIG Fig. 4 ), which separates the TV 51 from the utility 61. A cancellation of the separation from the supply network 61 is z. B. manually via an operating element 63 on the activity detector 56 or else via the control element 62 or the control unit 53 possible. In this case, embodiments are also possible which detect a desired reactivation of the TV set 51 on the basis of a user action (eg actuation of a remote control) and then cancel the power interruption of the activity detector 56. It is understood that any other home automation devices can be connected via the radio system 55 to the control unit 53. In particular, any other consumers can be provided be, which are assigned to monitor an activity more activity detectors. The monitored consumers can then be defined as scenario-typical consumers.

In summary, it should be noted that the method according to the invention for controlling building services equipment, which are each provided with a control element for controlling activation, as well as the arrangement according to the invention for carrying out the method, make a selection of stored scenes comfortable for the user. In particular, the scene selection is completely automated, so that no direct interaction of the user is required for the selection of a suitable scene. Simply by activating a consumer typical of a scene, an automatic retrieval and setting of stored scene settings is triggered.

The programming and the associated local intelligence of the coupling units or the entire components such. B. controls or control units depends on the specific embodiment of an inventive arrangement or on the specific method used. Depending on the version, higher or lower intelligence is required. Due to the programmable logic units, however, the components can be freely adapted to the requirements. Thus, it is possible, if necessary, individual components of an inventive arrangement, for. As activity detectors to provide greater local intelligence than other components such. B. Controls.
